Commit Message

Adhemerval Zanella Netto Sept. 28, 2016, 12:15 a.m. UTC
From: Adhemerval Zanella <adhemerval.zanella@linaro.org>


Changes from previous version:

 - Add back x32 use of syscalls.list until x32 {INTERNAL,INLINE}_SYSCALL
   is not yet fixed [1].
 - Added a __libc_pwrite64 alias to pread64 for x86_64 (since now
   posix_fallocate64 will be use and it will call __libc_pread64).

--

This patch consolidates all the posix_fallocate{64} implementation for Linux
in only one (sysdeps/unix/sysv/linux/posix_fallocate{64}.c).  It also removes
the syscall from the auto-generation using assembly macros.

The macro SYSCALL_LL{64} is used to handle the offset argument along with
the new INTERNAL_SYSCALL_CALL macro to define correct argument count for
internal INTERNAL_SYSCALL call.

Tested on x86_64, i686, x32, aarch64, ppc64le, and armhf.

        * sysdeps/unix/sysv/linux/mips/mips64/n32/posix_fallocate.c: Remove
        file.
        * sysdeps/unix/sysv/linux/mips/mips64/n32/posix_fallocate64.c:
        Likewise.
        * sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fallocate.c: Likewise.
        * sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fallocate64.c:
        Likewise.
        * sysdeps/unix/sysv/linux/wordsize-64/posix_fallocate.c: Likewise.
        * sysdeps/unix/sysv/linux/wordsize-64/posix_fallocate64.c: Likewise.
        * sysdeps/unix/sysv/linux/posix_fallocate.c (posix_fallocate): Use
        SYSCALL_LL to pass both offset and len arguments.
        * sysdeps/unix/sysv/linux/posix_fallocate64.c (posix_fallocate64):
        Likewise.

What about the new definition I sent with fallocate update patch:

#define FAIL(...) \
  ({ \
     printf ("error: line %d: ", __LINE__); \
     printf (__VA_ARGS__); \
     printf ("\n"); \
     return 1; \
  })

I think I can rename to FAIL_RET to explicit state it returns and maybe
add a RET_EXIT with same logic but calling exit.
